Application May 2, 1952, Serial No. 285,773

6 Claims. (Cl. 116-135) This invention relates to a scoring or indicatordevice.

One object of the invention is to provide a simple scoring or indicatingdevice. Another object is to provide an indicator slider for use in aslot in a card or the like. Still another object is to provide a detentslide indicator which may be easily and smoothly moved from one fixedposition to another in a slotted card or the like.

These and other objects are attained by my invention which will beunderstood from the following description, reference being made to theaccompanying drawing in which Fig. 1 is a perspective view showing oneform of my scoring and indicator device following my invention;

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged fragmentary rear elevational view of the detentslider positioned at an indentation in the slot;

Fig. 4 is a similar fragmentary rear elevational view showing the detentslider positioned midway between indentations in the slot; and

Fig. 5 is a front elevational view of the detent slider.

Referring to the drawings, a preferred form of my invention is shown inFig. 1 which consists of a cardboard base plate 11 which is providedwith one or more grooves or slots 12, each having one straight edge 13and an opposite wavy or undulating edge 14. A detent slider 15 isadapted to slide in the grooves or slots 12, the slider consisting of aback-plate 16 which is wider than the slots 12 and holds the body 17,which is attached to or integral therewith, protruding forwardly throughthe groove so that it may be pushed along the groove by a finger. Theslider body 17 is of the same width as the minimum width of the slot 12.The slider is provided with a crescent shaped cavity 18 extendingthrough the back-plate and into the body 17, the cavity ends 19 beingnarrowed to hold the ends of a flat leaf spring 20, and the widenedcentral portion being arranged to permit the bending of the leaf spring.Adjoining the crescent shaped cavity 18 at its center there is a lateralcavity 21 also extending through the back-plate 16, this lateral cavitybeing adapted to seat a roller 22, which rests on the leaf spring 20.The roller 22 is held by the spring to protrude through a centralizedopening in slider body 17 so that it is held above the edge of the body17 of the detent slider which is adjacent to the wavy or undulating edge14 of the slot 12 thereby permitting the roller to make rolling contactwith the wavy edge of the groove 12. A guide 23 is provided on the frontedge of the body 17 of the slider which with the back plate 16 serves toretain the slider in the slot as the wavy edge 14 thereof contacts theroller 22. As the slider passes the humps on the wavy edge 14, theroller 22 presses the spring into the widened central portion of thecavity 18.

The guide tab also serves as a pointer to the indicia marked at theindentations along the undulating slot.

The detent slider 15 is retained in the grooves or slots 12 by theback-plate 16 of the slider and the guide tab 23, but may be moresecurely held in the groove by a closure plate 24 which is attached atthe back side of the base plate 11, there being a spacer 25 between theclosure plate 24 and the base plate 11 to permit free movement of theslider in the grooves.

In the preferred form shown, the indentations have been given numericalindicia, and it will be apparent that other markings may be useddepending upon the use to which this device is to be put, for example,it may be used 2,704,048 Patented Mar. 15, 1955 as a scoring card or asa reminder for household purchases, and for a stock indicator, or thelike.

The advantages of my device are generally its low cost and simplicity offabrication. The slider does not wear out the grooves or slots becauseof the roller detent which moves against the wavy edge of the slot, theother edge being straight and not subjected to excessive wear. Theslider may be positioned at any desired indentation by merely pushing itlongitudinally in the slot until the desired position is reached, thespring pressed roller holding the slider in the indentation. The rollerpermits the smooth sliding of the slider in the wavy edged slot.

I claim:

1. A scoring or indicator device comprising a base plate having a slotwith one undulating edge and one straight edge, a detent slider adaptedto be moved along said slot, said detent slider comprising a bodyprojecting into said slot, and a spring pressed roller mounted in acavity in said body, said roller being exposed through an opening insaid body and pressing against said undulating edge and said sliderbeing held in place between the edges of said slot.

2. A scoring or indicator device comprising a base plate having a slotwith one undulating edge and one straight edge, and a detent slideradapted to be moved along said slot, said detent slider comprising abody projecting into said slot, a roller mounted in a cavity in saidbody, said cavity having an opening adjacent said undulating edge,whereby the cylindrical surface of said roller contacts said undulatingedge; a leaf spring mounted in a cavity of said body adjacent saidroller cavity, said spring pressing upon the cylindrical surface of saidroller opposite said undulating edge, and means on opposite faces ofsaid body for retaining said slider in the slot of said base plate.

A scoring or indicator device comprising a base plate having a slot withone undulating edge and one straight edge, and having indicia adjacentthe indentations of said undulating edge, and a detent slider adapted tobe moved along said slot, said detent slider comprising a body havingone side adapted to slide on the straight edge of said slot in said baseplate, and having an opposite side adapted to slide along the humps ofsaid undulating edge of said base plate, a roller mounted in a cavity insaid body, said cavity having an opening adjacent said undulating edge,whereby the cylindrical surface of said roller contacts said undulatingedge, a leaf spring mounted in a cavity of said body adjacent saidroller cavity, said spring pressing upon the cylindrical surface of saidroller opposite said undulating edge, and means on opposite faces ofsaid body for retaining said slider in the slot of said base plate.

4. A scoring or indicator device comprising a base plate having a slotwith one undulating edge and one straight edge, and having indiciaadjacent the indentations of said undulating edge, and a detent slideradapted to be moved along said slot, said detent slider comprising abody having one side adapted to slide on the straight edge of said slotin said base plate, and having an opposite edge adapted to slide alongthe humps of said undulating edge of said base plate, a back plate onsaid body wider than said slot, a roller mounted in a cavity in saidbody, said cavity having an opening adjacent said undulating edge,whereby the cylindrical surface of said roller contacts said undulatingedge, a leaf spring mounted in a cavity of said body adjacent saidroller cavity, said roller resting on its cylindrical surface upon saidspring, and a guide tab on the front of said body extending over saidundulating edge.
